The Thorium AR is the largest and heaviest, the Cerium LT is the smallest and lightest. The Agrium is about 26% lighter than Thorium on average. However, it only packs down approximately 15% - 20% smaller. Whereas the Cerium LT is about 35% lighter than the Thorium, and packs down to more around half the size.
Web5.10 Thorium. Thorium (Th, atomic number 90, in group 3 of the periodic table of elements, standard atomic weight 232, density 11.78 g/cm 3) is the first member of the actinide series. Thorium is a naturally occurring soft, silvery white radioactive metal present in very low levels in water, soils, rocks, plants, and animals.
WebSpecific Activities. The term “specific activity” is defined as the amount of radioactivity – or the decay rate – of a particular radionuclide per unit mass of the radionuclide. For example, the specific activity of Ra-226 is 1, meaning that one gram of Ra-226 contains one (1) curie (assumed to be uniformly distributed throughout that ... shower 34 x 48WebApr 14, 2024 · However, the Thorium is 6.4 ounces heavier at 1 pound 2.2 ounces, doesn’t pack down as small, and costs $50 more.
